  • How many times can a passive optical network split light

    How many times can a passive optical network split light

    By connecting with OLT and ONU, the fiber splitter can achieve split ratios of 1:2, 1:4, 1:8, 1:16, 1:32, and more. Optical splitters take a single light source (a single fiber optic strand) and refract and duplicate it multiple times to "outbound" fibers. A fiber broadband provider typically determines and overall split ratio for the network, such as 1x32 or 1x64, and uses combinations of splitters to meet that ratio with each PON port. 1x32 splits were common in North America for G-PON architectures. Fiber optic cabling uses light to transmit signals, and this light can. The passive optical splitter is essential for splitting a single Point-to-Multi-Point (P2MP) physical fiber network.
